A soil repair construction device

Abstract

The invention discloses a construction device for soil remediation. The device comprises a rack and further comprises a material scattering unit and a walking unit, wherein the material scattering unit is fixedly installed on the upper portion of the rack; the walking unit is fixedly installed at the bottom of the rack; and the material scattering unit comprises an installation plate, a supportingshell, a storage bin, a connecting cylinder, a cylindrical shell, a sealing cover, a first motor, a conveying shaft, a spiral blade and three linear blades. According to the invention, a constructionarea in unit time can be effectively increased; construction efficiency is effectively improved; granular chemicals in the storage bin can be prevented from spilling out; rainwater can be prevented from entering the storage bin through a feeding hopper to soak the granular chemicals, so the problem that the granular chemicals cannot be thrown out from the interior of the cylindrical shell due tomelting can be effectively solved; the walking unit is adopted for driving the device to walk, so the labor intensity of constructors can be effectively reduced; and a prepared protective layer can prevent the situation that a large number of the granular chemicals adhere to the inner wall of the storage bin and are difficult to clean.

Description

technical field [0001] The invention relates to the technical field of soil restoration, more specifically, it relates to a construction device for soil restoration. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out plans for the treatment and restoration of contaminated soil, thus forming a new soil restoration industry. [0003] Chemical soil remediation is the most commonly used method of soil remediation. It generally sprinkles granular agents for soil repair on the soil to be repaired, and the purpose of soil repair is achieved through the reaction bet...

Problems solved by technology

[0003] Chemical soil remediation is the most commonly used method of soil remediation. It generally sprinkles granular agents for soil repair on the soil to be repaired, and the purpose of soil repair is achieved through the reaction between the granular agents and the pollutants in the soil. The soil remediation construction device in the prior art has a small construction area per unit time and low construction efficiency, and the granular medicine inside the storage bin is easy to spill out during the construction process, and rainwater can also enter the storage bin through the hopper The internal soaking of the granules often causes the problem that the granules are thrown out due to the melting of the granules; secondly, the soil remediation construction device in the prior art generally uses human power to push it to walk, resulting in labor intensity for the construction personnel. Larger; in addition, the soil repair construction device in the prior art, the inner wall of its storage bin often adheres to a large amount of granular agents and is difficult to clean
